Formatted Abstract/Summary

Fringing coral reefs are developed adjacent to the islands within Moreton Bay, near Dunwich on the western side of North Stradbroke Island, and along the southwestern shores of the bay between Point Halloran and Wellington Point. Between Wellington Point and Cleveland Point reef growth is almost continuous for 10 km, but rarely exceeds 5 m in thickness. This reef began to develop approximately 7500 years B.P. upon a seawardsloping laterite platfonn. Coral growth did not keep pace with rising sealevel. Portions of the reef may have reached the intertidal zone about the same time as those reefs at Mud Island where uranium series dates of 4100 to 6000 B.P. have been obtained. Subsequently the back-reef area has been filled with terrigenous and bioclastic sediments. A distinctive tidal flat zonation has developed. Mangroves have developed in relatively recent times, having firstly colonized the upper intertidal surface of the reefs (north of Empire Point) or the landward side of beach ridges (shores of Raby Bay). Organic mud produced by the mangroves severely inhibits coral growth and the intertidal surface of the reef now consists of dead Acropora, whereas living corals (Faviidae) are restricted to the subtidal areas. Seaward progradation of the mangroves is very limited, however, landward extension is evident in some places.
